Retrofitting a CO2 Capture Unit with a Coal Based Power Plant, Process Simulation and Parametric Study

Sukanta Kumar Dash and Leena H. Wadibhasme
Abstract—In this work flowsheet simulation of a coal fired power plant retrofitted with a CO2 capture unit has been carried out in the AspenPlus process simulator platform. The simulation is an attempt for the detailed process involved in CO2 capture starting from generation of flue gas, CO2 capture by monoethanolamine (MEA) and regeneration of solvent using unit operation models available in Aspen Plus and appropriate calculator blocks wherever necessary using FORTRAN codes. The parametric study includes effect of absorber column height, regenerator pressure, on reboiler heat duty and power plant efficiency. Parametric study such as energy penalty on the power plant, reboiler duty of the capture unit, evolution of energy requirement has been done and presented. The contribution of desorption energy is about 47% of the total capture energy and the power plant penalty is about 30% lower when low pressure steam has been utilized to supply heat energy to reboiler.

Index Terms—CO2 capture, MEA, absorption, coal-fired power plant, simulation.
